I too am a little confused why some people don’t seem to be understanding what
I’m talking about. It has to be mostly me.
What happens to the dispersion of debris from a rocket that ‘comes in hot’ from
let’s say less than 45 degrees vertical?
Would it be different for a nose with sand vs. a nose with nails and epoxy?
Or, how about a rocket that becomes a ‘land shark’ and comes apart as it skims
the ground?
I’m not a PI attorney and far from it, but would there be additional problems
if someone was injured by a rocket that contained bullets, etc. vs. sand.
Maybe people shouldn’t give any consideration to what goes in their rockets
when it comes to dead mass? Stuff that does nothing but adds mass. I will,
but that’s my choice. Some projects are really unique and may actually require
high densities. I’m thinking most don’t and having the center of the dead mass
back slightly because of the lower density will not make a difference. People
seem to accept things that make large differences all the time and don’t blink.
And, for the stuff I’m building that has a lot of metal components, you will
never see those projects at a ROC launch. It’s just to dangerous for the venue.

Well, Smith is going to get a kick out of this, but I thought this was done
last night and when I woke this morning and saw all the emails, I said, ‘oh
man.’ I tried to read all the emails that came to me on this subject.
However, some where blocked because of my system’s choices for junk mail. I
bet a forum wouldn’t do that.
This topic is interesting and was posted as an example of how chat operates
when there’s a subject that could be controversial. It was not designed to be
a waste of time. For example, the same day I received lakebed reports posted
over 10 days from the launch. Did I consider getting this group of emails a
waste of my time? Yup, I did. Still, not everyone did, and I see that too.
But, it’s chat and I get them all.
So, I wake up in the morning and 10 people have posted replies, comments, and
even direct questions to me. How do I answer them?
Here’s one: To Allen: No
Oh, and there’s another one I didn’t see. And, some funny comments I need to
read through.
I made the subject line, Prohibiting Metal for Nose Weight. I didn’t list
things that I thought were particularly bad like nails, shot, bullets. Also, I
didn’t put rocks in the subject line. Although kids probably insert rocks in
the nose for weight.
Someone said it would be better to have a large solid mass free falling then a
bunch of bb’s. My point was don’t use either.
Yeah, I didn’t give the perfect answer or solution to my subject line, but I
did give some alternatives. Just saying, before you use nails and epoxy, think
if you can use something else. There are things that would be a public
relations nightmare to explain.
And, to Allen, please don’t be offended. I was just saying “No” to make a
point. Your post is interesting, but that’s not what I thought the major
problem is with using pieces of metal. Although, the two types hitting
something like an RV might yield different results. But then, Myth Busters is
pretty much gone.

So, can I get back to my rocket projects? ??

BTW, Allen - I was thinking more about your scenario and my first assumption
was that you were saying that the lead is already a lump, and sand, due to
heat, would become a lump too, so there's no benefit to use sand over lead.
Plus I was thinking that even superheated and fused, the lump of glass would
probably be a bigger lump than the lead and could actually be worse than lead
because it occupies more space. However, I was thinking more and I'm wondering
now if the heat from impact would render either material molten and simply
fragment into tiny shards either way? What do you think? Although from a safety
aspect, this is all meaningless, since these things occur at impact and if that
impact was a car or a person, the damage or injury would be the same, correct?
